Higher, more stable yield with ultra-early seeded wheat

Seed wheat as soon as feasible after soil temperatures reach 0C, and prior to soils reaching 7.5–10C, with an optimal seeding rate of 40 seeds/ft2, and at a shallow seeding depth. Ultra-early seeded wheat increased grain yield and stability compared to current seeding practices. Using…

Conserva Pak seeding

Wider row spacing may be possible in wheat

Wider row spacing in wheat is possible – up to 16 inches – but producers need to monitor their plant density to ensure they are reaching an adequate stand establishment to achieve optimum yield, especially since all seeding equipment may not maintain separation of seed…

Mature oat heads

Impact of seed size and seeding depth on barley and oat production

Large seed and shallow seeding independently improved organic barley and oat production. In organic production, pre-seeding tillage is an important weed management strategy, however this can cause drier seeding conditions. To compensate, greater seeding depths are often used, which may reduce crop performance. A 2-year…

Assessing sunflower seeding and N rate

An optimum seeding rate between 30,000 and 35,000 seeds/ac for hybrid 63A21 sunflower, and between 40,000 and 45,000 seeds/ac for open-pollinated AC Sierra was determined under no-till cropping systems in Saskatchewan. At N fertilizer prices of around $0.50/lbs., the recommended N fertilizer rate based on…

milling oat trial

Maintaining test weight in milling oats

Seeding early should increase the likelihood of harvesting quality grain before weathering, but this did not guarantee higher yields or higher test weights. Generally, 71 lbs. N/ac resulted in optimum test weights and often produced optimum economic returns. Selecting a variety with genetics for high…

seedling pea

Pea oat intercrop has potential

Intercropping may be beneficial when the desired crop is field pea, with potential contributions to weed suppression and reductions in lodging. There was no indication of a yield advantage to intercropping peas and oats. If profitability can be derived from reductions in in-crop herbicide use,…

ripe oat

Maximizing economic return in oats

A nitrogen fertilizer rate of 89 lbs. N/ac provided the most consistent economic returns when oat prices were between $2.50 and $3.00 per bushel. Fungicide application did not provide a benefit at any N application rate. In an effort to maximize yield and quality, some…

2635 vertical tillage

Vertical tillage no more effective than managing crop residue with the combine

Managing flax residue with vertical tillage, tandem disc, or rake and burn did not produce significantly higher yield for three subsequent wheat, pea and canola crops than chopping and spreading straw with the combine. Limited differences in soil attributes were observed, and they were diminished…


Pollinators increase yield and mitigate drought impacts

Pollinators increased yield by promoting earlier flowering and reducing loss associated with drought. However, pollinators were unable to compensate for suboptimal seeding rate or low nitrogen fertility. Get more bang for your buzz. This project consisted of three experiments that investigated whether pollinators could help…


Understand the limitations of combine grain-loss monitors

Existing combine grain loss monitors could not be correlated to an actual grain loss measurement. However they did provide an indication if grain loss was increasing or decreasing with different feed rates. You can’t manage what you can’t measure. That adage from the business world…
